Raghuram Rajan of the University of Chicago talks to Romesh Vaitilingam about his book 'Fault Lines', in which he outlines the deep systemic problems in the world economy that threaten further financial crises – high US inequality, patched over by easy credit; excessive stimulus to sustain job creation in times of downturn; and the choices of Germany, Japan and China to focus on export-led growth rather than domestic consumption. The interview was recorded in London in July 2010.
